AUTOMATIC WARDROBE.

Specification of Letters Patent. 1 Patented July 1, 1919.

Application filed April 17, 1918 Serial No. 229,025.

To all whom it may concern :j 7

Be it known that I, JOHN CI-IOMA, a subject of the Emperor of Austria, residing at Pittsburgh, county of Allegheny, and State of Pennsylvania, have invented certain new and useful Improvements in Automatic Wardrobes, of which the following is a specification. I

This invention relates to improvements in looks and particularly to types adapted to be applied to wardrobes, bathhouses, toilets, and the like, which are operable by the insertion of a coin, coincident with a proper key. i

The principalobject of the invention is to provide a lock, the bolt of which isynorlnally maintained in a forward or locked position, and not permitting the bolt to. be retracted except upon the entrance of a proper coin. i

A further object is toprovide a dial or target, designating whether or not the apartment is in use, which is QXh'lbItBd;CO-lIICI- dent with the operation of the bolt, and to. further provide means whereby upontthe insertion of a proper coin the bolt becomes amenable to the action of the key. These andother like objects are .attaine 1 by the novel construction and combination of parts hereinafter described and shown in the accompanying drawings, forming a material part of this specification, and in which Figure 1 is a front elevational view show-M mg a serles of wardrobes, or the like, and

indicating the application of the invention.

Fig. 2 is an enlarged vertical sectional view taken through the lock.

Fig. 3 is an enlarged front elevational view of a singlewardrobe or compartment, parts being broken away in order to show the application of the invention.

Fig. 41 is a vertical sectional view taken on line 4-4 of Fig. 2, and

Fig. 5 is an enlarged transverse sectional view taken on line 5-5 of Fig. 3.

In the drawings, the numeral 10 indicates the base of a series of wardrobes or the like, over which extends a ceiling 11, end walls 12, and partitions 13 between which are pivoted the doors 15, the pivots 16 being arranged centrally of the doors at the top and bottom thereof and consisting of cylindrical projections, in the upper of which is engaged the inner, bent end of a spiral spring 18, secured by a screw or like fastening 19, within a recess 20 in the ceiling 11, the arrangement of the spring being such as to normallymaintain the door in a closed position, at all ti1nes.

In the upperportion of the doors 15 is an opening 22, covered by a slide 23 movable between fixedguides 2 1 secured to the inner surface of the door, the slide bearing any desired designation as Free or numerals representing the number of the particular compartment. r

This slide is operated through a bar 25 engaged at its lower end with the slotted long arm 26 of a bell-crank lever pivoted on the interior of the door by a pin 27 the opposite end 28 of the lever being engaged with an extending end 29 of the lock bolt.

so that as the latteris operated the slide is moved vertically within its guides, indicating upon its face whether or not the compartment is in use.

The bolt mechanism comprises a casing.

33 is formed at the end of the bolt, connect-:

ing with the extension 29 and containing a slot 34 slidable upon a fixed pin 35 by means of which the bolt is guided. The front end of the bolt engages normally, when in a. locked condition withina keeper 37 fixed in the partition 13.

Formed integral with the connecting element 33 is an angular lug 38 engageable with the front end 39 of a bell-crank lever pivoted on the pin 4:0, the longer arm ll of the lever extending slightly toward the front and being formed into a cup 42, the bottom. 43 of which is pressed upward by the flat spring 4 1, so as tomake contact with the lower end of a rectangular tube 15, the tube being secured by the flanges 4:6 to the upper portion of the lock casing 30 through which extends an opening 47 adapted to receive a coin of theproper denomination. The coin, passing downward through the tube 45, drops upon the bottom 43 of the cup, its weight liberating the short arm 39 of the bell-crank lever and permitting the bolt to be moved rearwardly by the spring 32.

In order to close the slot against the insertion of a coin when the bolt is retracted, an

' site side of the tube pivoted to the bolt 31 by the pin 53 is a lever 54, tulcrumed on the pin 55, its upper end enga ing by the pin 56 with a sliding element 5% which, operating in conjunction with the element 51 prevents insertion of a coin when the bolt is at the lower end of the coin tube, it

enters a compartment 60 formed in the bottom of the lock casing, and passes from there through a passage 61 to a coin drawer 62, from whence it may be recovered by one having the proper key thereof.

To prevent the insertion of spurious coins or the like, a guard 64, with its lower flange 65 is secured to the top of the lock casing 30 the same being arranged so that coins passed into the body thereof may drop freely into the tube, while larger articles are prevented from being entered.

Arranged below the main bolt 31 at the front end thereof, is a block 70 having a recess 71, containing a compression spring 7 2, pressing against the head 73 of a plunger 74, resting against the interior of the lock casing 30, immediately below the bolt. A lug 75 formed integral with the block 70 is eontractable with the key 7 6 so that as the key is entered and turned therein, it will cause the block 70 to move.

A lever 80, pivoted on a projecting pin 81, is pivotally engaged at one end with the block 70 and at the other end with the bolt 31, so that as the key is turned and the block projected outwardly, the bolt is caused to move by reason of the lever 80 in an opposite direction, so as to be wholly retracted from the keeper 37, permitting the door to be unlocked.

It is to be noted however, that unless a coin has been inserted, and the arm 39 of the bell-crank lever removed, the key will be ineffective in operating the bolt. In operation, a coin having been inserted through the opening 47 and the key entered in the usual manner, it causes the bolt to move rearwardly, thereby permitting the door to be opened, simultaneously moving the plate 23 into position to indicate that particular compartment is being used, at the same time the rearward movement of the bolt closes the coin opening, preventing the insertion of other coins until the compartment has again been locked.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is.

In a look of the character described, a casing, a bolt slidable in said casing, a bell- -crank lever pivoted in said casing, having its shorter arm secured to an extension of said bolt, its longer arm formed with a cup adapted to form the bottom of a coin chute, a spring for retracting said bolt upon the operation of said longer arm of the bell crank lever by a coin, an arm secured to the upper ed e of said bolt having an inturned upper en adapted to enter through an opening into the coin chute, a lever pivotally secured intermediate its ends to said casing, and with its lower end pivotally secured to the upper edge of said bolt, a sliding element pivoted to the upper end of said lever and adapted to enter said coin chute opposite to said inturned upper end oi said arm, and means for retracting said bolt after its operation.

In testimony whereof I have afiixed my signature.

JOHN CHOMA.
